7 '0 all whom it may concern:

lie it known that l, JASPER BLACKBURN, a citizen of the United States'and resident of Webster Groves, St. Louis county, Mis' souri, have invented certain new and useful Improvements in Qombined'lnsulator and lily-Clamps, of which the following-1s a specification containing a full, clear, and er;-

sitely extending cablestrands having overtapping bights extended through openings formed in theinsulating body, and a pair of devices which are secured to the free ends of said strands at distances of separation approximately the width of the insulator body in order to minimize compression of the insulator body incident to strains on said strands andboltless guy clamps carried by each of said devices and arranged on median. lines thereof.

With the above purposes in View my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claims andillustrated by the accompanying drawings, in which- Figure 1 shows in elevation a device embodying my invention as in use; i

Fig. 2 is a transverse sectional elevation through the insulator; and

Fig 3 is a longitudinal sectional elevation through one of the boltless clamps.

Referring by numerals. to theaccompanying drawings: d designates an insulator, preferably constructed of porcelain or analogous material.

Formed through the body of the insulator are the oppositely arranged openings 5, and

leading from said openings to opposite ends of the insulator body are the channels 6.

7 and 8 designate cable strands which etitend in opposite directions having their bights occupying the openings 5 and their adjacent body portions occupying the channels 6.

9 and 10 designate devices constructed as integral units, each comprising a pair of outside. sockets 11 which taper or converge to ward the insulator l. the median lines of said pairs of sockets 11 being spaced apart distances equivalent to the spacing apart of median lines of the bodv ortions of the v strands 7 and 8 occupying the channels 6.

Formed at each free end of each of the.

strands 7 and 8 there is a bight 12 which is arranged to embrace a wedge 13, and said bights and said wedges coiiperatenvith said sockets to formboltless clamping devices.

Formed as a part of the integral units '9 and 10 intermediate the sockets 11 are the v sockets 14 which taper or diverge toward said insulator 4, and arranged to occupy the sockets 1-; are wedges 15 which are arranged to be. embraced by the ends of guy wires 16, and l? to be united, which ends have formed therein bights embracing the wedges 15 and are. inserted with said wedges through the sockets 1d.

insulator bodies such as are usually constructed of material possessing great tensile strength, but when subjected to torsional strains or compression are likely to shatter %*or this reason I have designed means for he ding the bodies el the" cable strands connectcd with the insulator body in absolute parallelism so that when they are subjected to teusional strains there will be no tendency towards. compression of the insulator body between the parallel portions of the strands.-

lt is to observed that the intermediate sockets 1eurc arranged in such manner that tensional strains applied to the guy ends 16, and 17 will be in the same parallel line, hence there will be no tendency toward a careeni'ng of either of the devices 9 or 10, or the insulator body i.

l. claim: r

1. in a device of the class described, a guy clamp cast integral and provided with two outside parallel casings spaced apart and having "formed therein parallel flaring sockets which flare in the same direction, a

wedge provided with a groove located in each outside socket, an intermediate casing projecting beyond the two outside casings and provided with a daring socket flaring in an opposite direction to the flare of the first mentioned sockets, and a wedge provided with a groove located in the socket of the intermediate casing.

:2. In a device ofthe class described, a guy clamp cast integral and comprising two out side parallel flaring sockets which are spaced apart and iiare in the same direction a wedgeshapcd plate provided -with a groove located in each of the outside sockets,

an intermediate socket flaring in the opposite direction to the flare of the outside sockets, the said intermediate socket beginning on a transverse line substantially at the eenter of the two outside sockets, and a Wedge shaped block provided with a groove located in the intermediate socket.

A 3. A combined insulator and guy clamp comprising a pair of guy clamps each east integral and provided with two outside tapering sockets which flare in the same direction, Wedge shaped blocks provided with grooves located in said sockets, an intermediate socket projecting beyond the out ide sockets, and. a wedge shaped block provi ed with a groove located in the intermediate socket of each guy clamp, an insulator block located between the clamps, and a pair of JASPER BLACKBURN.
